Depicts: Io, Jupiter
Copyright: J. Spencer (Lowell Observatory), and NASA

This picture is taken in March 1994, when Io was still "smooth". Compared with the newer image (search for opo9537 for comparison or opo9537b for the newer image) one can see that Io is still undergoing some geologic activity.
